Mississippi Mud Cake Recipe
Ingredients
For the Cake
- 1 cup unsalted butter, softened
- 1 ½ cups granulated sugar
- 1 ½ cups all-purpose flour
- ½ cup cocoa powder
- 4 large eggs
- 2 teaspoons vanilla extract
- 1 cup chopped pecans
- 4 cups mini marshmallows
For the Icing
- 16 ounces confectioners’ sugar
- ½ cup whole milk
- ½ cup cocoa powder
- ¼ cup unsalted butter, softened
Instructions:
Preheat and Prepare
Preheat your oven to 350°F (175°C).
Grease a 9×13 inch baking dish thoroughly.
Make the Cake Batter
In a large mixing bowl, beat together the softened butter and granulated sugar until creamy.
Add the eggs one at a time, mixing well after each addition.
Gradually add in the flour and cocoa powder, mixing until well combined.
Stir in the vanilla extract and fold in the chopped pecans.
Bake
Pour the batter into the prepared baking dish, spreading it evenly.
Bake in the preheated oven for 25 minutes or until a toothpick inserted into the center comes out clean.
Add the Marshmallows
Immediately after removing the cake from the oven, sprinkle the mini marshmallows evenly over the top.
Allow the marshmallows to sit and soften for a few minutes, then spread them gently to cover the top of the cake.
Prepare the Icing
In a medium bowl, mix together the confectioners’ sugar, cocoa powder, and softened butter.
Gradually add the milk, stirring until the icing is smooth and creamy.
Finish the Cake
Once the cake has cooled slightly, pour the icing over the marshmallow layer, spreading it evenly.
Let the icing set before serving.
Variations and Substitutions:
One of the beauties of Mississippi Mud Cake is its flexibility. Here are some variations and substitutions to tailor this cake to your liking:
Nut Variations
Swap pecans for walnuts, almonds, or hazelnuts for a different flavor and texture.
For a nut-free version, simply omit the nuts or replace them with additional marshmallows or chocolate chips.
Marshmallow Alternatives
If you prefer, use marshmallow fluff instead of mini marshmallows. Spread it over the hot cake for a similar effect.
Chocolate Chips
Add a cup of chocolate chips to the batter for an extra dose of chocolate.
Sprinkle chocolate chips on top of the marshmallows before adding the icing for a gooey, chocolatey topping.
Flavor Enhancements
Add a teaspoon of espresso powder to the cake batter to enhance the chocolate flavor.
Mix a tablespoon of bourbon or rum into the icing for an adult twist.
Healthier Options
Substitute half of the butter in the cake with unsweetened applesauce to reduce the fat content.
Use a sugar substitute like Stevia or Splenda for a lower-sugar version.
Different Toppings
Top the cake with a layer of crushed graham crackers or cookies for added crunch.
Drizzle caramel or peanut butter sauce over the icing for an extra layer of flavor.
Frosting Options
For a different twist, use a cream cheese frosting instead of the traditional chocolate icing.
A peanut butter frosting pairs wonderfully with the chocolate and marshmallow layers.
